Chapter 400 King's Landing
"Why is it so slow! Go to the kitchen to help. There are a lot of people entering Baiyun Temple today, and there is not enough manpower. We have to cook our own meals. If we run out of ingredients later, we will have to starve."

Qingyun's tiptoe appearance happened to be bumped into by Hu Caiting who was passing by holding firewood.

But to his surprise, Hu Caiting acted as if nothing had happened, just urging him to help quickly.

Qingyun obediently agreed, and followed Fourth Sister to the kitchen.

Qingyun's brain short-circuited along the way, and he didn't know to take the firewood from the fourth sister's hand.Hu Caiting was so angry that he kicked the kitchen door open, and said coldly to Yin Seke who was busy boiling water and washing vegetables: "I brought you your man. How to use it is up to you .”

"Oh, even if it's fourth sister's confinement, she can't afford it. I'm busy here, so you'd better keep it for yourself."

The word forbidden was indeed used too much, Qing Yun couldn't help but frowned, just as he was about to speak, Zu Dingzhi came up to him, put his finger on his lips and winked at him desperately, trying to persuade him to keep silent.

The emotional intelligence of tech geeks is not high, it just grows longer and sees more.This kind of enemy and friend relationship between girls, when the needle point is sharp, then there will be a long period of annealing and cold war. After that, if there is a scene where the two girls are fighting against each other, the two will return to normal. It's time to mix honey with oil, and the cycle goes on and on.

Just now, the two girls did not know what kind of tacit understanding they reached, and the hot war suddenly turned into a cold war. Although there was no more tension, the atmosphere seemed more tense.

"Fifth brother, help me light the fire."

"Brother, come and help me add water."

Four gazes came at the same time, and the two voices were in no particular order.

Jizhi patted Qingyun on the shoulder, looked at him with pity, and carefully "slid" out from the gap between Qingyun and the door frame.

"Come here soon!"

The two women shouted this sentence at the same time.

"The gentleman stays away from the kitchen!" Qingyun dropped a sentence from his book bag, turned around and wanted to escape.

A blow stick and a spatula stopped at the same time.

Qingyun definitely didn't dare to resist in front of the two girls. He watched them tie himself to the stool, and he was still secretly rejoicing: "It's good to be tied, it's good to be tied!"If I tie them up, I won't be forced to make so many weird choices!
But obviously he was still too naive.

He is the battlefield of the Cold War!
"The tofu flower is ready, just need some salt." Hu Caiting snorted coldly.

"How can you add salt? Tofu flower must add sugar to taste." Yin Seke hurried to grab the salt jar.

"Add salt!"

"Add sugar!"

"Ask Fifth Brother!"

"it is good!"

Four eyes focused again...

I should be on the roof, not in the house... See how "sweet" you guys are...

Qingyun looked up at the sky and kept silent, thinking that he could escape the catastrophe by being silent.

"He doesn't talk!"

"Then feed him and watch his expression."

"Okay, my sister has an idea."

"Sister comes first!"

"Okay!"

Qingyun was fed with two spoons in turn, and his mouth tasted salty and sweet, like knocking over a five-flavor shop, he hesitated but couldn't resist.

"He shook his head. He doesn't seem to like sweet tofu much."

"He avoids your spoon, he doesn't eat salty tofu at all."

"Who said he won't eat my tofu?"

"He only eats my tofu!"

……

Qingyun burps the 140th second.

Ji Zhi helped him get a glass of warm water, and looked at his roommate with pity, "Fish and bear's paws, you can't eat them cold and mixed, they are easy to hiccup."

Qingyun nodded wearily, as if suddenly remembered something, reached into his bosom, took out a porcelain bottle, and handed it to Tiezhi, "Mr. Huayang entrusted me to give it to you, he said you know how to use it."

When he opened the vase, he couldn't see the contents clearly under the light.

First, he fanned the mouth of the bottle cautiously, tried the smell, but found nothing, so he took a piece of white paper and shook out some of the contents of the bottle.

"Is it salt? Or sugar?" When asked this question, Qingyun couldn't help hiccupping again, the 140th and third.

On the white paper are several transparent crystal particles, which resemble salt grains.

Ji Zhi shook his head, he knew that the things specially given to him by the master would not be so simple.

But it is colorless and tasteless, and it is impossible to tell what it is just based on its appearance.He took one at random and threw it at the flickering candle.

Snapped!
The colorless particles exploded in the lamp flower, drawing out an emerald green flame, just like a ghostly cremation arc.

Qingyun shrank his head and neck back in fright, and the 140th four hiccups were forcefully pushed back before reaching his throat. The endless hiccups were actually frightened.

But there was no abnormality in Jizhi's expression, he could basically tell that the particles in the porcelain bottle should be some kind of nitrate.A hundred nitrates are bathed in fire, and the flame colors are different. The master's "Hundred Nitres Flame Dance Record" expresses the meaning at the beginning.So he had long expected the appearance of colored flames, and green was the result of feedback.

The color is green. In the teacher's notes, it corresponds to copper, normal lead (lead), Japanese lead (zinc), tashan lead (thallium), 镔 lead (manganese), barite lead (barium), and halo lead (molybdenum). , dead crystal lead (antimony) and many other colors of lead nitrate.

The crackling sound of the explosion indicated that the lead nitrate was not stable.

Jizhi waved his hand again and drew a wisp of light brown smoke from the explosion. After sniffing it lightly, he confirmed that these particles were positive lead nitrate.

There was a relieved smile on his face, obviously he had understood the master's intention.

"This, is this the salt used to attract ghosts?" Qingyun's theoretical knowledge is obviously not enough to gain insight into the truth.

"Recruiting ghosts? Do you think I can recruit ghosts?" Mozhi pointed to his nose and reasoned with Qingyun.

Qingyun shook his head. In this respect, he was even more absolute than his teacher, Mr. Huayang. He was an absolute atheist, and Mr. Huayang also studied physiognomy.This kind of nagging thing obviously wouldn't be his fault.

"This thing is dedicated to Wei Wang's flattery. I will use it to perform a trick in front of Wei Wang and his officials. When the trick is completed, there will be an uproar. Now is your chance."

"A chance to rescue the eldest princess?" Qingyun seemed to have realized something.

"Yes!", one of them looked confident.

"Can it cause such a big commotion? I'm a little curious. I'm sure I won't be able to witness it live. Second brother, can you show me the show first?"

Qingyun knew that the trick that was so favored by Ji Zhi must be extremely amazing, and his curiosity was ready to move.

"No! The quantity may not be enough. Besides, I have to prepare a small prop."

Takumi flatly refused.

"""""Knock on the blackboard time"""""

There are still some knowledge points in the first two chapters that have not been covered.Because two books are being updated at the same time recently, in order to ensure continuous updating, let's continue to wait for the next article.

We only talk about some small knowledge points that appear in this section.

First review two concepts:

Lead generally refers to all metals other than hardware, not just corresponding to today's lead metal.On this point, there has been a lot of development before.

Nitrate refers to salt ore.The salt here is a chemical salt.

We have also introduced Tao Hongjing's research on flame reaction before.

Here we only pick the category of green flame color for summary.

It's time to test your junior high school chemistry level:

The halogen salt of copper, the flame color is blue-green.The flame color of zinc is close to it.

The flame color of barium, manganese and molybdenum is yellow-green.

Lead, antimony and thallium are green or light green.

Orthodox lead is lead, and Japanese lead is zinc, as has been mentioned before.

Some other names are derived from limited fiction:
It is a mountain of lead, coded from its mountain stone, and thallium is a very rare metal element.The most common ore is associated with pyroarsenite, which looks somewhat like a crystal lead column.

Tin lead, as mentioned above, Tin iron beneficiation contains manganese.

Barite lead, from the most common barium ore, barite.

Molybdenite, molybdenite, the most important mineral of molybdenum, is covered with shiny scales with metallic luster.

Dead crystal lead, the most important antimony ore - stibnite, looks like crystal clusters, but it is dead gray.

The so-called positive lead nitrate here is exactly lead nitrate, and its thermal decomposition reaction is a common preparation reaction of nitrogen dioxide.Nitrogen dioxide, with a pungent smell, brown-red, a small amount of gas diffuses in the air like an explosion residue.

Extra question after class: Using lead nitrate to design amazing magic, which chemical reaction can you think of first?
Read this book, pick the knowledge points, and naturally get the junior high school chemistry competition level.

In addition, the most important sentence summary.

These seem to be the common sense of modern chemistry, but they are actually the research category of the ancient and serious alchemy.

Magic has never been magic, and mystical methods are not mystical methods, they are just science that is not understood by the times.
